This disclosure relates to an active medical device which includes a generator for producing multiphase nerve stimulation pulse trains, each pulse train including at least one stimulation pulse preceded by a precharge pulse and ending with a passive discharge pulse. The active medical device also includes a sensor configured to output a control signal representative of a physiological and/or physical parameter capable of being influenced by the output of nerve stimulation pulse trains. The active medical device also includes an automatic charge compensation control circuit configured to receive at the input the control signal output by the sensor, determine an amplitude and/or a precharge pulse time as a function of at least one predetermined criterion, and output to the generator a precharge pulse control signal to be produced at the output.

Active electrical nerve stimulation medical device, with automatic charge compensation control

A device for treating sleep apnea by discriminating between successive sleep stages of a patient includes a generator configured to produce stimulation pulses, a stimulator that receives the stimulation pulses produced by the generator and delivers stimulation to the patient, a sensor configured to measure a biological parameter of the patient, and a controller. The controller is configured to determine a state of the patient based on the biological parameter, perform a sleep analysis based on the state of the patient, activate the generator to trigger production of the stimulation pulses, determine a variation of the biological parameter subsequent to the production of the stimulation pulses, determine a response of the patient to the stimulation pulses according to the variation of the biological parameter, and determine a sleep stage of the patient based on the response.

Device for discrimination of stages of a patient's sleep

A device for treating sleep apnea in a patient through stimulation. The device includes a generator configured to produce stimulation pulses, a stimulator that receives the stimulation pulses produced by the generator and delivers stimulation to the patient, and a controller. The controller is configured to determine a sleep state of the patient, adaptively control the generator based on the sleep state where the sleep state includes a plurality of sleep stages, and modulate a stimulation energy of the stimulation pulses produced by the generator based on the sleep stage of the patient.
